cluster time-service ntp status show

Display status of the node's NTP client

Availability: This command is available to cluster administrators at the advanced privilege level.

Description

The cluster time-service ntp status show command displays the status of the associations between the cluster and external network time servers that use the Network Time Protocol (NTP).

Parameters

{ [-fields <fieldname>, ...]
If you specify the -fields <fieldname>, ... parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.
| [-instance ]}
If this parameter is specified, the command displays detailed information about all entries.
[-node {<nodename>|local}] - Node
If this parameter is specified, the command displays information related to associations on the specifed node.
[-server <text>] - NTP Server Host Name, IPv4 or IPv6 Address
If this parameter is specified, the command displays information about the associations related to the specified NTP server. The server should be specified as it is configured in the cluster time-service ntp server show command.
[-server-address <IP Address>] - Server IP Address
If this parameter is specified, the command displays information about the associations related to the NTP server with the specified IP address.
[-is-peer-reachable {true|false}] - Is Peer Reachable and Responding to Polls?
If this parameter is specified as true, the command displays information about associations with the NTP servers that have been successfully polled.
[-is-peer-selected {true|false}] - Is Peer Selected as Clock Source?
If this parameter is specified as true, the command displays information about associations with the NTP servers that have been selected as the current clock source.
[-selection-state <State of NTP Peer Selection>] - State of Server Selection
If this parameter is specified, the command displays information about associations with the specified selection state.
[-selection-state-text <text>] - Description of Server Selection State
If this parameter is specified, the command displays information about associations with the specified selection state description.
[-poll-interval <integer>] - Poll Interval (secs)
If this parameter is specified, the command displays information about associations that have the specified polling interval.
[-time-last-poll <integer>] - Time from Last Poll (secs)
If this parameter is specified, the command displays information about associations that are polled at the specified time.
[-offset <double>] - Offset from Server Time (ms)
If this parameter is specified, the command displays information about associations with the specified offset from the NTP server.
[-delay <double>] - Delay Time to Server (ms)
If this parameter is specified, the command displays information about associations with the specified travelling time to the NTP server.
[-jitter <double>] - Maximum Offset Error (ms)
If this parameter is specified, the command displays information about associations with the specified offset error from the NTP server.
[-reachability <Hex String>] - Reachability of Server
If this parameter is specified, the command displays information about associations with the specified reachability to the NTP server. Reachability is specified as a hexbyte that has a bit to represent the success of each of the last eight polls of the specified server. A set bit represents a successful poll. The least significant bit represents the most recent poll, the next most significant bit the poll before that, and so on.
[-server-stratum <integer>] - Stratum of Server Clock
If this parameter is specified, the command displays information about associations with NTP servers with the specified clock stratum.
[-server-reference <text>] - Reference Clock at Server
If this parameter is specified, the command displays information about associations with NTP servers using the specified clock as reference.
[-reported-errors <NTP Peer and Packet Errors>, ...] - Reported Packet and Peer Errors
If this parameter is specified, the command displays information about associations with the specified errors.

Examples

The following example displays the status of the NTP associations of the cluster:
cluster-1::*>cluster time-service ntp status show
Node: node-1
Server                  Reachable  Selection State                Offset (ms)
----------------------- ---------  ------------------------------ ------------
ntp1.eng.netapp.com          true  Currently Selected Server            39.122
ntp2.eng.netapp.com          true  Candidate Server                     37.786
2 entries were displayed.
	
The following example displays the status of the association with the specified external NTP server:
cluster-1::*>cluster time-service ntp status show -instance -server ntp1.example.com
